Effect of Light Intensity on Photosynthesis

Easy Data Representation Interpreting Experimental Data

A group of students conducted an experiment to examine the effect of varying light intensities on the rate of photosynthesis in aquatic plants. They placed samples of Elodea in water and exposed them to three different light intensities: low, medium, and high. The amount of oxygen produced was measured over a two-hour period. The results are shown in the table below:

Light Intensity (Lux) | Oxygen Produced (ml)
Low: 50 | 2 ml
Medium: 150 | 6 ml
High: 300 | 15 ml

Based on this data, which statement accurately describes the relationship between light intensity and oxygen production during photosynthesis?

Oxygen production decreases as light intensity increases.

Oxygen production increases as light intensity increases.

There is no correlation between light intensity and oxygen production.

Oxygen production is constant at all light intensities.
